Abstract : In this report an analysis is made of the different mathematical problems arising in practical applications of the new gravity reduction theory of Bjerhammar. The body of the report is to a great extent concentrated upon the solution of the basic integral equation of the theory. Different methods of solutions developed by A. Bjerhammar and W. Foerstner are discussed. An improvement of the methods are suggested, which makes it possible to introduce a great number of unknown coefficients in the linearized equations without being forced to increase the order of the approximating polynomials. The transformation of the integral equation from the sphere to the plane is analyzed in detail. Finally, new formulas are derived, making it possible to integrate the socalled x and yparameters for an arbitrary location of the actual point of computation. (Author)
